2 Christian Education Since all Christians have become by rebirth of water and the Holy Spirit a new creature so that they should be called and should be children of God, they have a right to a Christian education. A Christian education does not merely strive for the maturing of a human person as just now described, but has as its principal purpose this goal: that the baptized, while they are gradually introduced the knowledge of the mystery of salvation, become ever more aware of the gift of Faith they have received, and that they learn in addition how to worship God the Father in spirit and truth (cf. John 4:23) especially in liturgical action, and be conformed in their personal lives according to the new man created in justice and holiness of truth (Eph. 4:22-24); also that they develop into perfect manhood, to the mature measure of the fullness of Christ (cf. Eph. 4:13) and strive for the growth of the Mystical Body; moreover, that aware of their calling, they learn not only how to bear witness to the hope that is in them (cf. Peter 3:15) but also how to help in the Christian formation of the world that takes place when natural powers viewed in the full consideration of man redeemed by Christ contribute to the good of the whole society. Wherefore this sacred synod recalls to pastors of souls their most serious obligation to see to it that all the faithful, but especially the youth who are the hope of the Church, enjoy this Christian education.
